Has there been any solution to this I have missed since the end of this thread, or possibly one in the works?
Like Donk I am hoping to find a way to import a pls or m3u of radio stations directly into the "Radio" tab list of stations. It seems now only an OPML file can be imported, and these are not common for radio station playlists. I understand this may not be an easy task, as the radio OPML/xml used by MB has fields not normally contained in m3u/pls files, while the station's image display link (if created) resides separately in the Library mbl file.
I posted a similar request to the Wishlist a while back, but on seeing Donk's post thought I'd follow up on it here. As he mentions, it might also be possible to use a 3rd-party application/script to convert from m3u/pls to a MB compatible OPML/xml and import afterwards. If anyone knows of any such, that would be good information to share. Thanks for your attention!
